What codes can Amazon Gift Card Generator get me?You’ll be able to generate codes for $5, $10, $20, $50 and $100. When you select the desired amount you will be notified about the availability of the voucher code. For example, $100 codes are obviously harder to get so the available daily codes are 1 or 2. Amazon Gift Card Generator has an auto-update feature and gets the fresh list of codes on opening, including the available stock. Here’s a preview of an $20 amazon gift code.
